Problem linking Google Sheets

Hello, I have a problem with my DataStudio Report; I linked a Google Sheets file with it, everything was running fine until some structural changes in the source file (added a column and other changes). I did the "refresh fields" action and it seems like it didn't refresh it all, since my graphs and tabs in the reports are not linked anymore. The dimensions and associated metrics aren't all associated now, even when creating a new chart I can't make it work like it used to:

I think I had an internet connection dropout during the first "refresh" of the fields, but I don't know if it can have an impact.

Can anyone help me with this, I would really like to avoid to do the job back again, I have 8 programmed sheets in this report.Thanks in advance,
